From 1526a756fba5b1f2eb5001b8e8de2a0ea1bd2c66 Mon Sep 17 00:00:00 2001 From: "venkatesh.pallipadi@intel.com" Date: Tue, 18 Mar 2008 17:00:24 -0700 Subject: [PATCH] generic: add ioremap_wc() interface wrapper x86 has ioremap_wc for wc remap. Also introduce a generic ioremap_wc aliased to ioremap_uc so that drivers can use this interface transparently.
